I have done various sorts of field work on Eurasian lynx, brown bear, gray wolf, moose, hare, capercaillie, otter and other species across Sweden. Internationally, I have worked with puma and jaguar in Brazil and black-footed cat in South Africa. I have also done a bit of zoo-keeping and information work with snow leopard, Amur leopard and other carnivores.

Talking snow leopards at Järvzoo in Sweden.

A lot of what I do is information work, such as public talks, teaching, information videos, photography and articles. Some of what I’ve covered in magazines are the Persian leopard reintroduction programme, the Amur leopard situation, the effects of border fences on wildlife and the conservation project for the Iberian lynx in Spain. I wrote a book on snow leopards in Swedish together with Jan Fleischmann back in 2014, talking about the species’ biology, research, threats, conservation and much more. It is possible that the book will be released in English in the future.

One of my first projects was with Eurasian lynx in Sweden where we did snow tracking for one winter season and also interviewed locals about the decline of roe deer, its main prey. Eurasian lynx has since been one of my focal species. It is one of four large carnivores in Sweden.

Current focal species

I am currently focusing on the following species:

Eurasian lynx (Lynx lynx)

Puma (Puma concolor)

Jaguar (Panthera onca)

Snow leopard (Panthera uncia)

Gray wolf (Canis lupus)

Wild forest reindeer (Rangifer tarandus fennicus)

“Snöleopard” by me and Jan Fleischmann, released in 2014.

Some experience

Wildlife censuses of moose, roe deer, capercaillie, hare, lynx and marten by tracks, droppings and by helicopter throughout Sweden

Censused large carnivores for the County Board of Uppsala (Länsstyrelsen i Uppsala) 2017-2018

Field work on black-footed cat (Felis nigripes) in South Africa 2011, working with radio-collared cats

Authored the Swedish snow leopard book “Snöleopard” together with Jan Fleischmann, released in 2014

Field work at the Scandinavian Bear Project in 2006

Otter censuses, beginning in 2002 in Värmland, and also 2007 in Västerbotten

Media work about wildlife and nature for Mittmedia/Järvzoo and Biotopia

Led working groups organizing two carnivore symposiums in Sweden, in 2004 and 2012

Three field projects on Eurasian lynx. In the first we examined lynx movement and prey selection and also estimated the roe deer population in the study area based on observations by locals. We also investigated the local people’s views on what caused the roe deer population to decline

In the second lynx project, conducted a small field study with financial support from the Swedish Society for Nature Conservation investigating the possibility to develop tourism on Eurasian lynx

In the third lynx project, studied Eurasian lynx habitat and prey selection with GPS-collared lynx at Grimsö wildlife research station

Investigated puma livestock depredation in the Brazilian Caatinga in 2016/2017

Field work on moose & wildlife foraging on trees from Skåne to Norrbotten in Sweden 2010-2016 & 2018+
